Yaskawa Electric Corporation JUSP-NS500 Profibus Interface Module

The Yaskawa JUSP-NS500 Profibus Interface Module is a Sigma II (Σ-II) circuit board that functions as a Profibus-DP communication interface and indexer for Yaskawa servo systems. It attaches directly to SGDH Servopack drives and bridges the servo system with a Profibus network, enabling centralized control from PLCs or PCs. The module provides motion control capabilities, including positioning, speed control, and command execution, while serving as the communication hub for networked servo axes. Designed for SGDH Servopack drives in the 30 W to 55 kW range, it is mounted directly on the servo amplifier as part of the control assembly. Typical applications include CNC machines, robotics, packaging equipment, conveyors, and other industrial automation setups requiring synchronized motion and precise positioning. The JUSP-NS500 is listed as obsolete/legacy, with newer controller solutions replacing it. Common replacements include the JUSP-NS300 Profibus Module, the MP2600iec Single Axis Controller, and the JUSP-NS115 Communication Module.
